CARL CHRISTIAN BURMEISTER, OF COPENHAGEN, DENMARK.

MOTOR.

SPECIFICATION forming part of Letters Patent No. 398,767, dated February 26, 1889.

Application filed April 2, 1888. Serial No. 269,408.

(No model.) Patented in Norway March 5, 1888, No. 831 in Italy March 5,

1888,110. 23,105; in France March 5,1888,N0. 189,122; in Belgium March 5,1888,N0. 80,871, and in Denmark May 23,

To all whom it may concern.-

7 Be it known that I, CARL CHRISTIAN BUR- MEISTER, a subject of the King of Denmark, 1

residing at Copenhagen, Denmark, have invented certain new and usefulImprovements in Motors, (for which I have obtained patents in the followincountries, viz: Denmark running from May 23, 1888; Norway, No. 831, March 5,1888; Italy, No, 2 3,105, March 5,1888; France, No. 189,122, March 5, 1888, and Belgium, No. 8t),87l, March 5, 1888,) of which the following is a specification.

My improvements, described hereinafter, ro- 1 late to centrit'ugals, or those machines con;- monly known under the name of milk-separators."

I work my machine by foot-power instead of the usual hand or steam power, byboth feet; at the same time, something after the stylcof ridingabicycle, and by conveying the motion imparted to the treadles to the vessel 1 containing the milktobe separated,by means of suitable gearing.

In order to make my invention more clear,

I refer to the drawings which form part of this application, in which similar letters denote similar parts throughout the ditfei'ent ti'gu res.

Figurel is a side elevation of my improved machine. Fig. 2 is a front view of the same. Fig. 53 is a part side view showing the gearing by which the power of the operator is transferred to the milk-vessel. Fig: I is a part front view of the same gearing.

'lhe emistruction of the apparatus is as follows: Thc milk-separating apparatus and d ri ving-gear are fitted to a suitable lmd-plate,

ll, while the seat I on which the operator sits, is fastened by the standard ll to a separate bed-platxc,1. The seat F can be brought nearer or taken back from the center of the d rivi ng-shaft C by means of the piece K, which is provided with a slot, and held fast by means of the bolt M, so as to suit the length of the l operators The seat F is provided with i a handle, G,by which the operator holds himi self steady while driving the machine. l The main driving-shaft C is provided with 1 double cranks E E, which are placed opposite to each other. On the same shaft C is fitted a large cog-wheel, B, which gears in the small. pinion N on the intermediate shaft, 0, and this intermediate shaft, 0, is provided with the large coarse-pitched wornrwheel P, which again gears wit-h the worm Q. on the vertical 1 shaft R, to which again is fitted the vessel A,

tor holding the milk or other substance. The operation of the machine is as follows: i The operator mounts the seat F, after having adjusted it to suit the length of his legs, so as the feet can eonfortably rest on the cranks E E when in their farthest position from him. i He then sets the machine in motion, working it like an ordinary bicycle, holding on by the handle G. The power so produced is conveyed through the geariu B N I to the worm Q. which is made to revolve rapidly at: the expense of very little power.

The operator can work this machine for hours without feeling exhausted, and at a regular motion, on account of the power being balanced.

Having fully described my invention, what I desire to claim and secure by Letters Patent of the United States is In centrifugals, the combination of the ad justable seat F and bed-plate I, with the double cranks E E, gearing B N, shaft 0, worm-wheel P, worm Q, upright shaft R, holder A, and bed-plate L, substantially as and for the purpose described.

In testimony whereof I all'ix my signature in presence of two witnesses.

CARL CHIN STIAN BURMEISTER.
